TWINT workflow

Step 1: Create a twint payment type resource. A resource ID is generated in the response and is used in the workflow to complete the payment.

Step 2: Make a charge transaction with the twint resource that you created.

Step 3: Forward the customer to the redirectUrl that is displayed in the charge response.

Step 4: Once the customer makes the payment on their bank portal, redirect the customer to the returnURL specified in the initial charge call.

Step 5: After the transaction, display the result to the customer in the front end of the online shop.
